Assessing linearity in structural equation models through graphics
(2008)While Structural Equation Models (SEMs) generally assume linear linkages between variables, it is a well-worn issue that this may not adequately describe the complexity and richness of social phenomena. For this reason, ... -
Un approccio di rete all'analisi delle relazioni amicali dei disoccupati nella città di Napoli
(2008)Several studies highlight that the labour market entry is strongly influenced by informal relational networks (friendship and kinship). Given that informal networks have a relevant role in job position, the present work ... -
Strumenti di analisi per esplorare reti di collaborazione scientifica
(2008)The study of the scientific collaboration networks is one of the traditional areas of interest in Network Analysis framework. The aim of the paper is to explore co-authorship networks, where researchers are connected ... -
Winds of change and policies. The inequality - employment trade-off in the OECD
(2008)Using a data-set of OECD countries from 1980 to 2004, we assess the crosscountry evidence on the trade-off between wage inequality and employment performance by relying on Data Envelopment Analysis, a nonparametric technique ... -
Efficiency gains and mergers
(2008)In the theoretical literature, strong arguments have been provided in support of the e ciency defense in antitrust merger policy. One of the most often cited results is due to Williamson (1968) that shows how relatively ... -
Privatization in oligopoly: the impact of the shadow cost of public funds
(2008)The aim of this paper is to investigate the welfare effect of privatization in oligopoly when the government takes into account the distortionary effect of rising funds by taxation (shadow cost of public funds). We analyze ... -
Dropping out of University of Salerno: a survival approach
(2008)The aim of this paper is to analyse and model the interval of time between the first enrolment at University and the first occurrence of non-enrolment, so that the event of interest is the dropping out of University. The ... -
The determinants of research quality in Italy. Empirical evidence using Bibliometric data in the biotech sector
(2007)Does the collaboration between firms and universities or other research organisations improves the quality of research? Why do firms collaborate with public research organisations? The rising importance of university- ... -
Identifiability for mixtures of distributions from a location-scale family with uniforms
(2007)In this paper we study the indentifiability of a class of mixture models where a finite number of one-dimensional location scale distributions is mixed with a finite number of uniform distributions on an interval. We define ... -
Relazioni tra imprese e università nel biotech-salute dell'Emilia Romagna. Una valutazione sulla base della co-authorship delle pubblicazioni scientifiche
(2007)Questo lavoro analizza il tema delle collaborazioni tra istituti di ricerca e imprese e le loro evoluzioni recenti, evidenziando il ruolo che può avere in un tale tipo di analisi un indicatore relativamente poco utilizzato, ... -
Bias-corrected inference for multivariate nonparametric regression: model selection and oracle property
(2014)The local polynomial estimator is particularly affected by the curse of di- mensionality. So, the potentialities of such a tool become ineffective for large dimensional applications. Motivated by this, we propose a new ... -
GRID for model structure discovering in high dimensional regression
(2014)Given a nonparametric regression model, we assume that the number of covariates d → ∞ but only some of these covariates are relevant for the model. Our goal is to identify the relevant covariates and to obtain some information ... -
A general coalition structure: some equivalence results
(2013)The formation of coalition may imply some theoretical difficulties, such as costs arising from forming a coalition or sharing information among agents. In this paper we will assume that only a subset S of the set of all ... -
New insights on the relationships between geographic and institutional distance in research collaborations: a long period analysis
(2014)This paper analyses the relationship between institutional and geographic distance in scientific collaborations, evaluating the possible changes when a long period (sixteen years) is taken into consideration and discussing ... -
Nudging e Salute: un binomio possibile?
(2013)Il termine inglese nudging viene tradotto in italiano con la locuzione “spinta gentile”. Esso indica un’azione svolta dallo Stato diretta ad incentivare (o disincentivare) comportamenti individuali ritenuti benefici (o ... -
Asymmetry in the permanent price impact of block purchases and sales: theory and empirical evidence
(2012)This paper extends previous research which has examined the market impact of large transactions in bull and bear markets by examining the information effects of trades. Previous research has demonstrated that the information ... -
Third party punishment and criminal: an experiment with Italian camorra prison inmates
(2012)In Third Party punishment experiments (Fehr et al.; 2004), an agent may be punished for violating a social norm by an uninvolved observer - or third party - whose payoff is unaffected by the behavior of the same agent. In ... -
Optimal compensation contracts for optimistic managers
(2012)We study an employment contract between an (endogenously) optimistic manager and realistic investors. The manager faces a trade-off between ensuring that effort reflects accurate news and savoring emotionally beneficial ... -
Cooperative credit banks: some fundamental institutional features
(2012)The aim of this paper is to analyze individual preferences in relation to different job characteristics. This is an important issue in the light of the huge literature in labor economics and human resource management about ... -
How do the institutions involved in scientific collaboration deal with different kinds of distance? An analysis of the co-authorships of scientific publications
(2012)In the scientific collaborations among different institutions at least two types of distance may be identified: spatial and institutional. We talk about spatial distance if the institutions are located in different places; ...
